SEAL-Looney Y To all whom t may concern Beit known that I, EMIL vTYDEN, a citizen of the United States, residing at Evanston, in the' county of Cook and State of Illinois, have invented new and useful Improvements in Seal-Locks, of which the following is a specification, reference beingk had tothe accompanying drawings, forming a part thereof. i

The purpose of this invention is to provide an improved seal locking device, particularly adapted for securing telesco-ped members such asa can'body and its ltelescopedicover, or a box andits lid which shuts intothe box.

It consists inthe elements and featuresof n construction shown and described, as i'ndicated -in the claims. i In the drawings, the invention is shown as yapplied to acanhaving a telescopingjicover.

Figure 1 is a vertical section of a portion of a can body and cover and la seal-locking device embodying `this invention, vapplied thereto. Fig. 2 is a top plan view of the seal mount and seal therein detached from the can. Fig. 3 is a plan view of the blanks from which the seal boltis made by doubling it upon itself at aline indicated. Fig. et -is a view similar to Fig. 1, sliowinga 'modifiedy form of the invention. Fig. 5 is an inverted plan view of the form shown'in Fig. Ll. Fig.

6 is afplanview of the seal bolt for the device shown in F-igsl l and 5.- FF ig. 7 is a view similar to Fig. 1 showing a modilied forin of the device. Figq is a section at thegline S`8 onFig. 7 Fig., 9 isa plan view ofthe seal bolt suitable for use in the .forni of the device shown in Fig. 7.

In the drawings, 1 represents a portion of a can body; 2 is the cover forthe sametele` scoped therewith; rIlie cover has on its telescoped `portion an exterior .circumferentialgroove, 2a, for engagement of 'the' seal bolt. Upon the outside of the `neck-of the can body there' is secured the seal mount, 3, whichkis a bracket-like device riveted to the can neck,

y comprising a web, 3?, and two Lip-raises there from, 3b and 3C, each `having a seal aperture,;

the aperture, 3d, in the up-raise, 3b, isthat through which the seal bolt thrusts for locking, and the can bodyhas an aperture,1a, registering with said aperture, 8d, in 'position i yfor registering with the groove, 2a, of the' cover when the cover is in closed position. The aperture, Se, is extended down through the web, 3a, being made at the junction of.

such ',weakening being yinost convenientlyv yeffected by cuttingatransverseslot, 5, in

said ply, 5b@ The end portion of this ply kbeyond the slot, 5c, is 'designedfto receive, and vis shown as bearing,'an identifying" niark, and is preferably up-bent, as seen in Fig. 1, for the purpose of convenience in taking hold of this ply'for folding itxf'to secure it, as will belexplained. i

The can having beenk closed yby. telescoping` the cover withthe body tothe proper yposition,` the vseal folded as described is inserted, `folded end first, through the aperture, 3G,

far enough to permit the remote end ofthev lower. ply to `pass down along `the inner upraise, 3?,= to the aperture, 3d, therein, and is then thrust inward through said aperture,

4engaging the slot, 2a.; The operator now taking hold of the llip-bent` end of theupper ply will bend lit at the weakened line yof the slot,

5C, over the up'fraise, 3e, to the position shown" in dotted line in Fig. 1. The identifying niark on the `end portionv off: the seal thus bentbver, is made to read from the kside j which is yexposed uppermostuwhen it is thus bent, ywhich is the und'erforfinne'` -side..when theseal is folded before usef It is now impo-ssible to disengageth'eseal bolt for opening the can without bending back the marked r end of the seal lbolt `to its original position,

and in` such bendingitswill break by reason of wealreningz at the slot,f5c. It might be possible, however, `to bend .up the portion'of ioo the rlfl'ower ply of the seal between the two up-.raises,3b"and 3C, sufiiciently to disengage the bolt end ofthe saine from the groove, 2a, of the can cover; and tok prevent this being done,withoutk breaking theseal and so disy i closingthe tampering, the lower plyis weakened at afpoint ,which, when itis engaged for locking as described, stands intermediate the two upfiaises. This is most'conveniently done .byy cutting two notches, 5e and 5f, into theopposite edges at the point indicated.l

in the form shown in Figs. 4, 5 and 6, the

seal mount, 10, is a bracket riveted to the* side of the can neck as in the other form,

but having the seal seat on the under side of a horizontal web, 11, and bounded' by two verticallyfdepending fianges, 12, 12. A fla-t lug, 13, projects from the upper side of the web at the outer end. Projecting downward from the web midway in the wedge of the seal-seat, there is a hook-lug, 14, having its hook end projecting toward the aperture, 15,

through which the seal projects forlocking.

The seal in this formfof the `device is a strip,

1G, having a slot, 17, for receiving thev hook lug, 14, and anotherfslot, 18, for receiving the fiat lug or nose-piece, 13; and it is weakened for breaking at one end of the slot, 18, by across slot, 19, which opens into the slot, 1S, making the total opening T-shaped. The end portion of the seal beyond the slot, 18, is designed to receive the identifying mark, and the opposite end` is" the bolt end for thrustingthrough the aperture, 15.

The proportions of the seal and mount are such that for applying the seal and locking, the bolt end, 20, is inserted in the aperture, 15, and thrust there-through far enough to permit the aperture, 17, to receive the hook lug, 14, by swinging the seal up flat-wise against the under side of the web, 11. When thus applied, the bolt end, 20, `projects through the aperture, 15, farther than necessary for locking the can cover, and may be withdrawn a little distance, and this being done, the hook end of the lug, 14, engages the inner end of the aperture, 17, preventing the seal from being swung down again without being iirst thrust longitudinally. The distance of the slot, 19, from the slot, 17, with respect to the distance ofthe neck of the hooked lug, 14, from the end of the bracket, 4is such that it is necessary to thus withdraw the seal so as to engage it with the hook, 14, in order to fold the seal at the slot, 19, up around the end of the bracket to pass the nose or lug, 18, through the slot, 1S; and

,the length of the slot., 18,'is such that the seal being thus folded, the lug, 13, fully occupies the slot, prevent-ing any endwise .movement of the seal. The seal being weakened by .the slot, 19, as described, will fold sharply when bent by hand, andbeing thus folded, it will be seen that the seal cannot be withdrawn in any direction unless the seal is unfolded at the slot, 19, because so long as the end portion beyond the slot, 19, projects transversely ofthe end of the bracket, the seal cannot be pushed longitudinally inward to disengage it from the hook, 14,.anduntil it is thus disengaged'it cannot be dropped' down be slid longitudinally to disengage it from the hook, 14, andv until it can be thus slid longitudinally, it cannot be dropped down so as to be drawn back out of the aperture, 15, and therefore it is impossible to disengage the seal without rst breaking ofi1 the label end which is the purpose of the construction.

Fig. 7 illustrates a third modification of the invention in which the Seal, 21, is bent back upon itself at 22somewliat as in the first form,but is inserted directly `in the mount, 23, being passed under the upraise or abutment, 24, over the web, 25, andthrough lower ply, 21, which serves as the bolt is longer than the upper ply, 21h, of the seal and -is weakened by a transverse slot, 21C, which registers with the edge of the web, 25, when the bolt end is inserted in locking position. In this position the outer folded end, 22, extends beyond the abutment, 24, of the mount so that it may be grasped and swung downward, folding thelower ply of the seal the aperture, la, in the neck of the can. The

about the line of weakness at 21C, as the upperply, 21h, projects inward beyond this line this projecting portion will thus be swung up away from the lower ply, 21a, and back against the abutment, 24, serving as a stop to prevent withdrawal of the seal from the aperture, la. To defeat the possibility of raising the seal off the web, 25, and withdrawinga it obliquely upward past the abutment, 24, the skirt, 26, of the mount, 23, is provided with a flange, 26a, curved circularly about the edge of the web, 25, over which the seal is folded. Both plies of the seal strip are notched at 21d, for engagement with this flange, 26a, through the entire range of the folding movement, so that before the seal can be removed from the aperture, la, it

must be foldedback over this curved path to the straight position illustrated in full lines in Fig. `7, but such folding would certainly result in breakage at the line of weakness at 21C. kSince the notch, 21, is much wider than the thickness vof the flange, 26, the

give warning to an inspector that the locl had been tampered with. v

Incombination with a seal mount having an aperture, a seal comprising a strip haying one end `adapted to be thrust through saiduaperture in locking position, the mount 'having also an abutment facing the said aperture, the 'outer end of the seal strip being folded back toward the inner end which occupies the aperture, land the portion :of said strip betweensuch fold and the outer end engaging the abutment of the mount to prevent withdrawal ,of :the strip from the aperture, .l

2. `In combination with a seal mount having an aperture, a seal comprising a strip having one end adapted to be thrust through said aperture in locking position, the mount having also an abutment facing the said aperture, the seal strip being folded to bring its outer end portion into engagement with the abutment for preventing withdrawal of the inner end from the aperture, and said strip lbeingweakened at the-line'of such fold Y to insure breakage when unfolded for disengagement from the abutment. Y

3. In combination with a seal mount havmg an aperture, a seal comprising a strip having one end adapted to be thrust through.

said aperture in locking position, the mount having also an abutment facing the said aperture, the outer end portion of the seal being formed as a stopl engaging the said abutment to prevent withdrawal of the strip from the aperture and the portion ofthe strip between the aperture and the abutment beingweakened to insure breakage of such portion if bent.

4. In combination with a seal mount hav,-k ing an aperture, a seal comprisingy a strip having one end adapted to be thrust through said aperture inlocking position, the mount having also an abutment facing the said aperture, the outer end portion of the seal being formed as a stop engaging said abutment to prevent withdrawal of the stripy from the aperture, means 'on the mount adapted to prevent transverse displacement of the strip, and the portion of saidf strip between the aperture and the` 'abutment being weakened to insurebreakage of such portion if bent. f
